The analysis is fully automatic, indicates all tones detected in the measured FFT spectrum, selects the most prominent tone, and immediately delivers all parameters to report. When activated, tone assessment appears as a special cursor mode on the sound level meter.

Features

With this option is selected the appropriate measurement configuration is automatically selected, making it easy to set up FFT analysis that follows the ISO 1996–2 standard.

All details instantly

On completion of the measurement, the calculation of tonal parameters for all the possible tonal candidates in the analysis takes only a few seconds, after which the comprehensive list of results (Kt, δLta, Lpn, Lpti, Lpt, and Critical Band) is immediately available. The LAeq is measured simultaneously and the tone corrected rating level can be calculated on the spot.

Help to analyse the right tone

With the headphone output you can listen to a sine tone generated at the cursor position's frequency, and then compare it with the noise you measure - providing an intuitive and fast way to ensure you report data for the correct tone.
